I believe you are right and I did start looking at net/relayd. I gather it is not as fully implemented on FreeBSD vs OpenBSD. I don't see how this can work as "extra_address" is on a totally different network from what machine B is on... no packets for extra_address would ever appear on B's...

unfortunately networks M and N are physically separate and machine B does not have and cannot have a connection to network M (and thus cannot make use of the extra address on M). I suppose to rephrase and simplify, machine A has two address on network M and one on network N while machine B only...

I probably have the terminology wrong, but... I have two FreeBSD machines, A and B, and two networks, M and N. Machine A is connected to both networks, M and N. Machine B is only connected to network N. Although both M and N can get at the Internet, the firewall on N is far more restrictive...

Is there a good way to create an image backup of a disk to a tape under FreeBSD? Ideally the method could backup any disk, regardless of partitioning, filesystem type(s), etc., and allow easy cloning, restoration, reconstruction of the imaged disk onto a new, fresh disk (of equal or greater size).

yes, but as it turns out, the problem is not with the "echo" but "read", so "read -r" solves the problem.

I'm writing a shell script which processes a text file line by line and compares each line to string arguments passed down from the command line. Actually it is trying to solve the old problem of, if you have false hits in Procmail, how to you figure out which pattern is causing the problem...

You can probably do a tunefs -m 6 /dev/ada0s1a to free up a little extra space in the meantime. You'll have to do it in single user mode as / is active. Do you know what all that 17 GB is for? Make sure you don't have massive log files somewhere chewing up all that valuable space.

Re: Solid support for any common Linux filesystem? ZFS? Both can mount the same ZFS disk pool. VM: maybe, but would that allow access to the same filesystems? Would running on a Freebsd FreeBSD VM allow Linux to access files on a FreeBSD UFS?

I'm thinking of setting up a dual-boot FreeBSD/Linux computing server/machine and it would really help if the two OSs could share one large filesystem for data, user files, etc, in a way that both OSs have full and total support of that filesystem. This obviously rules out NTFS, FAT... is there...

The data won't just be MRI scans, but its true that probably most of the primary data is of the sort where it is collected and is usually not changed afterwards. However during the course of analysis probably a fair bit of storage would be used to store intermediates and results. So if the...

thanks for all the thoughtful replies... re: how much the data costs, etc. I understand this argument, and yes the data costs $100,000's to $mils to generate, not to mention years or more in time. Nevertheless the budget is the budget. It is not possible to go to the granting agencies (who...

use: medical research data, including MR imaging data, genomic sequencing data, microscopy imaging data, etc... backups: this is part of my question... I really only have dealt with and think of tapes... I don't quite grok using disks as backups unless they are going to be hot-removable... but...

Anyone have hints and experience building (or simply buying) file servers in the 300-500TB range? Is FreeBSD still a good solution for this scale? How should one deal with backups at this scale?

Re: Attaching an external Windows/DOS 3 TB hard drive via US My experience from one to two years ago is that NTFS support via ntfs-3g (FUSE) on FreeBSD is VERY marginal. It is maybe 90% for reading but only 50% for writing, i.e. if you want to read some files, or write a few files, it is...

Is there any storage technology that approaches $1/TB? Or even $10/TB? I'd like to store at least 0.5-1 TB "forever" for no more than $10. It should be on some kind of removable media not unlike a CDROM or tape cartridge.

I'm planning a new storage server, at least 10-30 TB. What is the current recommended way of backing up such a server... and I mean a real backup (off-site storage, restore multiple past states, etc). I'm still using tape for my smaller servers, but it seems expensive and unwieldy...

Where do you suggest getting the enclosures and other hardware to complete such a 12-drive system?

ok, well does anyone have FreeBSD ... - working on a laptop - with a USB 2.0 port - and an external USB hard DISK drive (preferably a Seagate) (working solidly)?

Laptop running off of AC but battery is also 100% charged and good. Commands, well actually I don't need to even use any commands before the drives start doing their disconnect/reconnect cycling. If I get far enough (sometimes the drives are "stable" for 1-5mins), I start with fdisk...

I'm having a problem using external USB hard drives with laptops and FreeBSD. I've tried several laptops (mostly Dell), several USB drives (external powered, Seagate), and FreeBSD versions 8.2 and 9.1RC3. The drive(s) keep disconnecting ("lost device") and reconnecting. The same drive(s) work...
